13. Use of a 3D Mathematical Model in Water Quality Management Billings Reservoir´s case / Utilização de modelagem matemática 3D na gestão da qualidade da água em mananciais - aplicação no Reservatório Billings
Mathematical modeling has proved to be an extremely useful technique in forecasting water quality. Because of different hydrometeorological conditions and the different ways in which land is used and existing infrastructure is managed, there is considerable variation in the volume and type of pollutant flowing into the receptor bodies. This has implications

14. Ecologia trófica de espécies alóctones (Cichla cf. ocellaris e Plagioscion squamosissimus) e nativa (Geophagus brasiliensis) nos reservatórios do rio Tietê / The trophic ecology of allochthonous species (Cichla cf. ocellaris e Plagioscion squamosissimus) is native (Geophagus brasiliensis) from the Tietê river reservoirs
A introdução de espécies nos ecossistemas pode levar a conseqüências difíceis de serem controladas, sendo que a competição por recursos alimentares talvez seja o principal meio pelo qual uma espécie introduzida possa afetar as espécies nativas, podendo ocasionar a extinção. Neste sentido, os estudos de alimentação tornam-se importantes ao forne

15. Distribution of Cladocera (Branchiopoda) populations on medium and low Tietê river reservoirs: a spatial and temporal analysis / Distribuição das populações de Cladocera (Branchiopoda) nos reservatórios do médio e baixo Tietê: uma análise espacial e temporal
Artificial reservoirs are ecosystems with broad economic and social importance; however, they modify hydrological and ecological characteristics of the environment, interfering on the organization of biotic communities, which, in turn, play fundamental role in the transference of energy in the ecosystem. Spatial and temporal organization may occur on these e

16. Analysis of distribution, density and toxicity of cyanobacterial blooms and its toxins in the reservoirs of Middle and Low Tietê river (SP) and its relation with limnological characteristics of this system / Análise da distribuição, densidade e toxicidade de florações de cianobactérias em reservatórios do médio e baixo rio Tietê (SP) e relação com as características limnológicas do sistema
Reservoirs in Brazil, particularly in São Paulo State, are important ecosystems which were built up successively in the last 40 years. Some of these reservoirs, mainly at the Middle and the Low Tietê river cascade system are eutrophic. Frequently cyanobacterial blooms are related to these eutrophic conditions which compromise the multiple use of the reserv

17. Composition, abundance and reproductive aspects of fishes from Álvaro de Souza Lima reservoir (Bariri, SP) and relationships with environmental factors of the system / Composição, abundância e aspectos reprodutivos das espécies de peixes do reservatório Álvaro de Souza Lima (Bariri, SP) e sua relação com as características ambientais do sistema
A construção dos reservatórios implica em alterações de caráter social, econômico e biológico, que podem interferir de maneira espacial e/ou temporal sobre o ecossistema. Neste contexto, as características das comunidades ícticas têm sido utilizadas para avaliação da degradação ambiental, por serem sensíveis indicadoras de estresses diretos o

18. Avaliação da qualidade de sedimentos dos rios Tietê e Piracicaba nos seus compartimentos de entrada no reservatório de Barra Bonita, SP / Sediments quality evaluation of Tietê and Piracicaba rivers in the entrance compartments of Barra Bonita reservoirs
Along the last decades, Barra Bonita reservoir has been suffering with its water quality degradation, once its majors tributaries (Piracicaba and Tietê rivers) are inserted in high anthropic development regions. The monitoring of the water quality has suffered substancial changes, when considering the sediment as an integrator site of the processes ocurred

19. Níveis de ocorrência de Hg total em peixes carnívoros das represas de Barra Bonita e Bariri, em função da variação de parâmetros biológicos e da presença de selênio.
The Barra Bonita and Bariri reservoirs, Medium river Tietê, São Paulo, Brazil, are used with several purposes as transport, provisioning, electric power generation, professional fishery and leisure. The region is surrounded by an industrial developed pole, receiving sewer of domestic and industrial origin, as well as the effluents of agricultural activitie

20. Diversidade de avifauna aquática nas represas do médio e baixo Rio Tietê (SP) e nos sistema de lagos do médio Rio Doce (MG) e sua relação com o estado trófico e a morfometria dos ecossistemas aquáticos.
Relationships between aquatic birds and the trophic state of freshwaters are not well known in tropical systems. In the present work the influence of some limnological variables on the structure of the aquatic bird comunnity was investigated for two distinct freshwater systems: The cascade of reservoirs in the middle and low portions of Tietê River (SP) and

21. Composição de rotífera em corpos d água da bacia do rio Tietê São Paulo, Brasil.
Rotifera composition in four Units of Management of Water Resources of Tietê River, in São Paulo State, was studied. Samples were obtained using a 35m plankton net pulled, horizontally and vertically, through limnetic and littoral regions and, afterwards, fixed with 4% formalin. One hundred and ninety nine taxa were identified. These belong to 23 families

22. Program of waste and sewage from small craft inland harbors, passengers waterway terminals and recreational boating in reservoirs. / Um estudo sobre a gestão de resíduos e efluentes em marinas, terminais hidroviários de passageiros e embarcações de turismo e lazer no Reservatório de Bariri/Hidrovia Tietê-Paraná.
The environmental aspects related to the daily operations in small craft inland harbors, in passenger waterway terminals, in leisure and tour vessels, in addition to other supporting facilities such as fluvial shipyards, indicate the need for adoption of sustainable models of management of such organizations, due to the fact that their activities are directl

23. Monitoramento de gases causadores do efeito estufa em reservatorios de usinas hidroeletricas
The proposal of this work was to evaluate, through field experiments using na static chamber, the contribuition of hydroelectric power generation to the greenhouse effect due to the evasion/invasion of CO2 at the water/air interface of reservoirs. The developde procedure uses na static chamber to colect CO2, what is then measured with the help of Flow Inject

24. PRODUCAO PRIMARIA E SUAS RELACOES COM ALGUNS FATORES FISICO-QUIMICOS EM RESERVATORIOS DO ESTADO DE SAO PAULO. / Primary production of Santos Bay, Sao Paulo state: aspects of the photosynthetic efficiency in a polluted environment
The present work is part of a 1argeT project entited "Typo1ogy of Reservoirs of the State of São Paulo". It was sponsored by FAPESP (Fundação de Amparo à Pesquisa do Estado de São Paulo - State Foundation for Research Support), and included the study of 52 reservoirs. For the present study, ten reservois were sampled four times during 1979. Seven of the
